## CRITICAL GUIDELINES

### Windows File Path Requirements

**MANDATORY: Always Use Backslashes on Windows for File Paths**

When using Edit or Write tools on Windows, you MUST use backslashes (`\`) in file paths, NOT forward slashes (`/`).

## Quick Reference

| Effect | Command |
|--------|---------|
| Scrolling credits | `-vf "drawtext=textfile=credits.txt:y=h-80*t"` |
| Typewriter | `-vf "drawtext=text='Hello':enable='gte(t,n*0.1)'"` |
| Fade in text | `-vf "drawtext=text='Title':alpha='min(1,t/2)'"` |
| Bouncing text | `-vf "drawtext=text='Bounce':y='h/2+50*sin(t*5)'"` |
| Karaoke ASS | Use ASS format with `\k` timing tags |
| Moving text | `-vf "drawtext=text='Move':x='w-mod(t*100,w+tw)'"` |

## When to Use This Skill

Use for **animated text and karaoke**:
- Music video lyrics with karaoke highlighting
- Movie-style scrolling credits
- Animated titles and lower thirds
- Typewriter text reveal
- Kinetic typography
- Countdown timers
